'BOTTLE-STOPPER FASTENER.

Specification of Letters Patent.

Patented Jan. 15, 1907.

T (all w/wm, it may concern.-

Be it known that I, CONRAD M. CONRAD- SON, a citizen of the UnitedStates, residing in the borough York, county of Improvements inBottle-Stopper Fasteners, of which the following is a specification.

This invention relates to and has for an object to provide an improvedstoppered bottle or jar, and particularly to means for securing taperedglass stoppers upon tapered glass seats,

In the drawings accompanying and forming a part of this specification apracticable embodiment of a form of my invention is illustrated.

Figure 1 shows a portion of a bottle in elevation, the neck being shownin vertical cen tral section and a stopper placed therein shown inelevation. Fig. 2 is an enlarged vertical section of the neck and mouthof a bottle; and Fig. 3 is the elevation of a stopper removed, showingthe position at about right angles to that shown in Fig. 1.

The bottle (designated in a general way by 5) is shown as having a neck6, which is provided with a tapered or conical seat 7 for receiving aclosure or stopper having a tapered or conical face 8. The mouth of thebottle is shown as provided with an enlarged bead portion 9, which willbe occupied, but not necessarily fitted by the shank portion 10 of thestopper. Such shank portion is shown as provided with. a protrusion 11,which when the stopper is being placed in position will traverse alongitudinally-disposed groove 12-, from which leads a transverse groove13, the upper face 14 of which latter groove is at a slight angle to theperpendicular of the axis of the bottle. The face 15 of the protrudingportion 11 is shown upon a corresponding angle for reducing theliability of chipping these faces when the stopper is placed in positionand turned by means, for instance, of the handle portion 16. Theengagement of the faces 14 and 15, at helicoidal, will firmly press theface 8 upon the seat 7 and the stopper will be held from accidentaldislodgement.

By having the conlcal faces inthe neck of least one of these being thebottle and upon the stopper ground to the same angle and formed so thatthe stoppers are interchangeable it is possible to proof Manhattan, cityof New vide for the form of locking above described, New York, and Stateof New s1nce Y ork, have invented certain new and useful i, make therewill be sufficient uniformity to this commercially feasible. Thecontacting surfaces for the being formed upon the same parts will notgrind together, with the bottle-stoppers now in use, which grindingtogether so securely wedges and locks the stopper in the bottle that itsremoval at times is impossible. In the present illustration the face 14occupies a helicoidal position and faces in a downward direction, thestopper-seat 7 facing upwardly angle, these as is the case when thebottle is in an upright posltion. The

conical seat expands outwardly. The tendency of the stopper 8 to risefrom the seat 7 will be prevented by the reaction of the face 15 againstthe face 14.

It will be noticed that the member 11 projects from that side of thestopper upon which the flat face of the handle portion 16 lies. This isa practicable way of making the stopper, sinceby placing this projectionat such a position one side of the mold may be prepared for it and itmay be drawn from the mold easily.

Having described my invention, I claim- 1. The combination with a bottlehaving an outwardly-expanding conical glass stopperseat and anangularly-disposed glass reaction-face, of a stopper having a conicalglass portion similar in angle to said seat and a glass locking portionfor engaging said reac tion-face.

2. The combination with a glass vessel having a glass closure-seat, of aglass closure having a glass face for seating on said seat, and saidparts having cooperating glass looking means for clamping said glassface and glass seat together in sealing relation.

3. A bottle provided with a neck, such neck having a conical glassstopper-seat, the

closure of the vessel month of the bottle having a channel parallel withits axis and an offset from said channel disposed at a slight angle totheperpendicular of said aXis, and a stopper having a conical glassportion corresponding with the angle of the seat in said neck and aprotruding IOO glass portion for traversing said channels and E andcooperating locking members carried by Io locking the stopper 1n sealingposition upon J said vessel and closure for locking sald glass saidseat. faces together in sealing relation.
